The purpose of this book is to share with science and health professions educators the exciting discoveries that are being made by the application of team-based learning (TBL) to the special challenges of modern medical education. Professors in these disciplines everywhere face three daunting challenges. First, an enormous amount of information must be learned, and it keeps growing. Second, students must learn how to use and apply that information in contexts that vary enormously between clinical cases and populations of cases. Third, in addition to these long-standing challenges, these educators, in response to public expectation, recognize the need for practitioners to have good people skills. This means learning how.
